Greg Dunn is a neuroscience PhD student at the University of Pennsylvania and an artist passionate about Japanese minimalist scrolls. While these interests may appear radically incongruous, Dunn's artwork suggests otherwise. The artist creates dazzling works of enamel, gold leaf and ink inspired by science.

Morning Glory Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States http://goo.gl/8MYsn

Temperature 171.6°F Dimensions 23x26.6 feet. Depth 23 feet. A deep, funnel-shaped pool with a dark blue center. The resemblance to the corolla and color of a morning glory is responsible for its name in the early 1880s. It has been a popular thermal feature and a symbol of Yellowstone. The early stagecoach and automobile road came within a few feet of this pool until 1971 when the road was rerouted.

Early visitors carelessly removed the delicate scalloped border and dumped debris into the pool. In 1950 the water level was lowered by siphoning which induced the pool to erupt. Socks, bath towels, 76 handkerchiefs, $86.27 in pennies, $8.10 in other coins came up; in all, 112 different objects were removed from Morning Glory. The debris had reduced the flow of water and contributed to the decline in temperature, causing bacteria to grow in the cooler yellow and orange edges of the pool.

Have you ever wondered why you get "brain freeze" when you eat something cold such as ice cream or a milkshake? That sudden pain in your forehead is known in medicine as sphenopalatine ganglioneuralgia.

It is caused by having something cold touch the roof of the mouth (palate), or the total immersion in water that is generally below 15°C (or 10°C or even 5°C for some acclimated open water swimmers).

Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation and teamwork, shedding new light on the origins of what it means to be human. The study appears online in the journal Proceedings of the Royal Society B and was led by scientists at Trinity College Dublin: PhD student, Luke McNally and Assistant Professor Dr Andrew Jackson at the School of Natural Sciences in collaboration with Dr Sam Brown of the University of Edinburgh.

The researchers constructed computer models of artificial organisms, endowed with artificial brains, which played each other in classic games, such as the 'Prisoner's Dilemma', that encapsulate human social interaction. They used 50 simple brains, each with up to 10 internal processing and 10 associated memory nodes. The brains were pitted against each other in these classic games.
